> 4000 mg/kg bw/d.
> 4.74 mg/L.
The LD50 studies presented indicate low
acute oral toxicity in rats, with LD50 values varying from >4,000 mg/kg
bw up to 7,334 mg/kg bw. Considering the history of human use of sodium
bicarbonate, the effects of oral exposure are well known due to
accidental and intentional ingestion by humans, and it is considered
safe to ingest up to 4 g/dose.
The inhalation toxicity study indicated a
low toxic potential, as the LC50 was >4.74 mg/L.

bicarbonate (2002), pg. 15]
Based on the results described, the substance does not need to be
classified for acute toxicity according to CLP Regulation (EC) No
